- FOSSA Systems
Participated · Equity · Jun 2026
FOSSA Systems uses a vertically integrated model to design and deploy low Earth orbit (LEO) satellite constellations, which the company says reduces constellation costs by an order of magnitude. Its approach is positioned to enable governments and corporations to deploy secure space strategies in months rather than years. The company has operational roots in Spain and Portugal and is led by founder Julián Fernández. Recent commercial and strategic traction includes selection into NATO’s DIANA program and expansion into the Japanese defense market. Financially, FOSSA announced a roughly €9.25 million financing round co-anchored by Índico Capital Partners to accelerate expansion and defense-market activities. Índico characterized its investment as a follow-on to earlier backing as part of a plan to scale the team into a global category leader.
- SatVu
Participated · Equity · Feb 2026
SatVu is a UK-based thermal Earth-observation company that captures 3.5-metre resolution infrared imagery day and night to provide intelligence on buildings, industrial sites, and other strategic assets. Its data helps government, defence, and industrial customers detect heat signatures linked to operational changes, assess readiness, and monitor climate-related emissions. The company currently operates a single demonstration satellite but is transitioning to a multi-satellite constellation; two new satellites are slated for launch in 2026 and a further three are already under contract. This expanded fleet will boost revisit frequency, enabling near-continuous monitoring of global activity. Beyond defence, SatVu’s imagery supports sectors such as steel, cement, data centres, oil & gas, and solar energy. Following the latest raise, SatVu has secured £60 million in total equity funding to date, providing capital for constellation build-out and commercial scaling.
- Interstellar Technologies
Participated · Series F · Aug 2025
Interstellar Technologies is a Japanese launch-vehicle company focused on building Zero, a two-stage, methane/liquid oxygen rocket designed to place up to 1,000 kg into low Earth orbit. The firm targets Zero’s maiden flight in 2027 and has already signed eight payload customers from Japan, Singapore, South Korea, and the United States for that launch. Prior to Zero, Interstellar flew the Momo suborbital rocket seven times between 2017 and 2021, achieving three successful flights. Beyond launch, the company is advancing a formation-flying satellite system meant to create a phased-array antenna for direct-to-device communications. Financially, Interstellar has now raised a total of ¥44.6 billion after closing a ¥20.1 billion Series F round in January. The new capital will fund continued Zero development, scale up manufacturing, and support the communications satellite initiative.
